You know if you had enough monsters and PCs you could have the whole thing circle around until the Wizard gets to grab someone and it's an ouroboros of grapple checks. Everyone garrotes/bites each other at the exact same instant and everyone dies, summoning Hulk Hogan and Andre the Giant from the center of the circle. The eternal struggle begins again in earnest.

Maybe Green Fighter planned to garotte Vampire B all along. Or maybe he wanted to attack VampB, and the player decided to drop weapon and quickdraw a garotte instead of using the weapon, just for laughs.
